/*
* The purpose of this code is to signal the operational status of a
* target which usually boots over the network; while running in
* PCBoot, a status LED is blinking. As soon as a valid BOOTP reply
* message has been received, the LED is turned off. The Linux
* kernel, once it is running, will start blinking the LED again,
* with another frequency.
